One of LCSG's objectives is to identify and implement sustainable dredge material disposal projects that will ultimately minimize the footprint and impact of dredge disposal sites in the Lower Columbia. The LCSG forms project teams and subcommittees to examine specific issues.

The group believes that collaborative, dredge disposal projects that can be achieved within a relatively short time frame will help build trust and better working relationships among stakeholders. The LCSG has established a Charter among Lower Columbia stakeholders from both the Washington and Oregon sides of the river.
